The bodies of the deceased officials have been recovered, SaudiNews50 reported late Sunday, after posting a video of the recovery efforts.

Eight people were on board the helicopter, including the Undersecretary and the Secretary of the Asir Region, Al-Arabiya reported, citing sources. None are believed to have survived the crash.

The incident occurred as the officials were on their way back from an inspection trip to al-Saida al-Sawalha Center in the municipality of Mahail Asir, it added. A video, believed to be the last one of Prince Mansour alive, was released by the channel, showing him and accompanying officials boarding the helicopter.

The ruling Saud family were recently thrust into the spotlight in connection with a wide-ranging crackdown on corruption, unleashed Saturday by the new all-powerful anti-corruption committee led by Crown Prince Salman. Hours after it was established, the committee ordered the detention of 11 princes and four ministers, as well as a number of former ministers. Among those arrested are Minister of the National Guard Prince Miteb bin Abdullah and Economy Minister Adel Fakeih, both sacked by Saudi King Salman bin Abdulaziz Al Saud the same day. Another high-profile target of the corruption purge is billionaire prince Al-Waleed bin Talal, nicknamed the “Arabian Warren Buffet” for his investment skills. According to Forbes, the prince tops the list the Middle East’s richest with a net worth of some $18.7 billion.
